hi i have a slight confusion..i got the above explanation but i have a doubt as in when u say int arr[5], arr is also the pointer to the first element of the array right?..so size(arr) shudnt be the size of pointer (which is int 4 byte address it holds of the first array element?) ..is it not interpreted this way?....and sizeof(&arr) looks like address of the pointer itself which also will be int (4 bytes)??
